This inventionrelates to book cover pro- 'tectors, and is applicable to books having stifl or semistifi covers, whether the object be toprotect the book or to improvethe ap- I object is to provide a cover protector which 15 is adjustable with relation to the thickness of the book to be covered thereby and having improved means to secure the same to a 'book. A furtherobject of the invention is the 9 6 provision of improved flapmeans for engag-" ing the cover protector with the inside faces of the covers of a book.

Other objects and advantages of the invention will become apparent as the speciand arrangements of parts hereinafter described in their preferred embodiments,

'8 pointed out :in the subjoined claims, and

illustrated on the annexeddrawing, wherein like parts are designated by the same reference characters throughout the several views.

Inthe drawing:

Figure 1 is a plan view of one pocket portion of the cover protector, embodying the, invention.

Fig. 2 is a plan view of the second pocket portion of the cover protector. V 7

Fig.3 is a plan view of the assembled cover protector in fiat open position with the book removed.

The advantages of the invention as here outlined are best realized when all of its features and ,instrumentalities are combined in one and the same structure, but useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the art towhich this invention apper'tains, that showingthe preferred exemplification of the I ing the covers of a book; Tlie' blanks may .be made of any suitablematerialp-fo-r exam- 1 protector to a book. The'fiapC may have,

the same may be incorporated in several-dif ferent constructlons. The. accompany ng drawingftherefore.1s subm1tted merely as invention. p

Referring in detail to the drawings, the book cover protectormay be made of apair ofbl'ank's 10 and 11, which'may be'built up 1 into pocket portions 10a and 11a for receivple p'aperQ- r "The blank 10 is provided with alined sections A513, C separated by parallel fold lines" 12,13. The sections B C maybecoeXten-Iv sive. in size with the book cover, while the,

sectionedis'of suflicient size to extend around f v the backfofthe' book and engage'the pocket portion 11a. :At the side of 'the" section'B there maybe providedflaps D along fold" lines 14, forfolding over on the inside of a book cover.-v Edges 15, 16 of the flaps D may be out along an angle toafford clearance in the. assembling and application of the cover reent-rant angular;edges 17 parallel {to the edges 16. Intermediate of the edges 17 and spaced inward of the ends 18 of the flap C, is a flaplet 1 9-that projects toward said ends. Differently stated. it will be perceived that the fiaplet is integralfwith the blank'10 and intermediate of the side flaps D. Adhesive is suppliedto the flaplet at 20 and also at 21 to the section C. Adhesive may also be applied to an edge portion 22 of the section A. The blank 11 is constructed in all respects similarly toblank 10, except that'section A is omitted. V In assembling the cover protector on a book,

sections B are placed against the outside of 9 the, book cover, flaps Dturned inward over the same, and section G turned inward overv flaps D and secured thereto with the adhesive. Then the fiaplets 20 may be secured to thein side face of the book cover. Finally, thesec tion A is foldedaround the back'o'f the book; and secured with'its adhesive to the pocket portion 11a; completing the cover protector.

It will be seenfthat since the flaplets 20 are small, the cover protector may be secured to the book cover at smallareas only, so that the book may not be mutilated especially when the cover protector becomes worn out and is replaced. The flaplets 20 facilitate assembling the cover protector snugly around the book, and as they aflord a secure non-stretching engagement, the cover protector is always neatly'and reliably retained on the book, and cannot be lost or accidentally removed, thus assuring constant protection for the book cover. c 7

Having thus described my invention, I

claim as new and desire to secure by Letters 1. A book cover protector'comprising two separate sections each having a pocket'for individually receiving one cover of a book, one of the sections-havinga large flap to extend around the back of the book and engage the other section, both sections having integral small inside projecting flap portions for attachment to the inside surfaces of the cov ers ofthe book, whereby the sections are'retained in engagement with the book covers, particularly at the free endsof the latter.

2. A book cover protector comprising two I v separate sections, each of said sections having spaced side flaps and one end flap joined together to form a pocket for each section, each of said end flaps having a small integral flap projecting therefrom intermediate the side flaps, the small flaps having adhesive on their the other section at a inner surfaces, one ofthe sections having a I large flap opposlte to its end flap for engaging 7 point remote from its small flap.

3. A book cover pocket portions for receiving thecovers of the book, each of said pocket portions having an integral non-stretching flaplet, sai'dflaplet H having adhesive to engage the saidcover, whereby each pocket portion isretained in' engagement on the book covers in the open and closed position of the book. o 1 In testimonywhereof I have signed my name to this specification.
